BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to vehicles, and more specifically to avehicle including a front row and a rear row of seats arranged in afore-aft direction.

2. Description of the Related Art

There is disclosed a large variety of multi-purpose four-wheel vehiclescapable of driving on uneven terrain.

For example, United States Patent Application Laid Open No. 2010/0314191A1 discloses a vehicle, which includes a pair of front wheels, a pair ofrear wheels, a frame, a roll-over protection cage, and seats. The framesupports the front wheels, the rear wheels, the roll-over protectioncage, and the seats. The seats are configured so that two persons sitside by side in a width direction of the vehicle in a front row, and twopersons as well in a rear row.

Aside from such a vehicle described above, there are also vehiclesconfigured so that three persons sit side by side in the width directionof the vehicle in a front row and three persons as well in a rear row. Aproblem, however, with this vehicle is that when the vehicle makesrolling movements, the person sitting in the middle tends to makecontact with the other two persons sitting on his/her sides. This candegrade the riding comfort of the person sitting in the middle.Therefore, a seat belt unit is required for a passenger who sits in themiddle of the front row.

However, there is a problem of where and how to attach a winding deviceand a shoulder anchor of the seat belt unit for the passenger sitting inthe middle of the front row. It is difficult to make an appropriatearrangement to securely attach these members while maintaining theriding comfort of the passengers in the rear row.

SUMMARY OF THE INVENTION

Therefore, preferred embodiments of the present invention provide avehicle that allows secure attachment of a winding device and a shoulderanchor of the seat belt unit for the passenger sitting in the middle ofthe front row while maintaining the riding comfort of the passengers inthe rear row.

According to a preferred embodiment of the present invention, a vehicleincludes a front row and a rear row arranged in a fore-aft direction ofthe vehicle. The vehicle includes a pair of front wheels; at least apair of rear wheels; a frame portion supporting the pair of front wheelsand the pair of rear wheels; a roll-over protection cage disposed abovethe front row and the rear row, and supported by the frame portion; apair of support portions extending in an up-down direction of thevehicle on a left side and a right side in a width direction of thevehicle, and connecting the frame portion and the roll-over protectioncage to each other; a cross member extending in the width direction ofthe vehicle between the front row and the rear row, and connecting thepair of support portions to each other; a first seat portion, a secondseat portion, and a third seat portion arranged in the width directionof the vehicle in the front row and supported by the frame portion; anda seat belt unit provided to the second seat portion. In this vehicle,the second seat portion is between the first seat portion and the thirdseat portion. The seat belt unit includes a belt member; a windingdevice to wind the belt member; a shoulder anchor slidably supportingthe belt member drawn out of the winding device; and a buckle portionlocated at an obliquely downward position from the shoulder anchor in afront view of the vehicle to fix the belt member. The winding device islocated at a position lower than the shoulder anchor; the cross memberconnects the pair of support portions to each other at a position higherthan centers, in the up-down direction, of the pair of support portions;and the cross member is located between an upper end of the shoulderanchor and a lower end of the winding device in the front view of thevehicle, and supports the shoulder anchor and the winding device.

According to a preferred embodiment of the present invention, a pair ofsupport portions that extend in the up-down direction connect the frameportion and the roll-over protection cage to each other, and areconnected to each other by the cross member. This improves the rigidityof the vehicle as a whole and securely fixes the cross member in thevehicle even if the vehicle is increased in size in the fore-aftdirection by including a front row and a rear row arranged in thefore-aft direction. The cross member that is securely fixed in thevehicle is located, in the front view, between an upper end of theshoulder anchor for a passenger sitting at the center in the front rowand a lower end of the winding device therefor. Therefore, it ispossible to dispose both of the shoulder anchor and the winding deviceadjacent the cross member, and to securely support the shoulder anchorand the winding device provided for the passenger in the center of thefront row by the cross member. The cross member extends in the widthdirection of the vehicle between the front row and the rear row, whilethe cross member connects the pair of support portions to each other atpositions higher than the centers, in the up-down direction, of the pairof support portions. This makes it possible to dispose the cross membersufficiently above seat surfaces of the seat portions in the rear row.As a result, it is also possible to dispose the winding device that islocated at a position lower than the cross member, sufficiently abovethe seat surfaces of the seat portions in the rear row; in other words,neither of the cross member and the winding device for the passengersitting at the center in the front row is disposed at a position lowerthan the knees of the passengers sitting in the rear row. Thisarrangement ensures the riding comfort of the passengers in the rearrow. As described above, it is possible to securely attach the windingdevice and the shoulder anchor of the seat belt unit for the passengersitting in the middle of the front row while ensuring the riding comfortof the passengers in the rear row.

Preferably, the vehicle further includes a first support portion that ispreferably U-shaped or substantially U-shaped and includes two endportions connected to the cross member, and a second support portionthat is preferably U-shaped or substantially U-shaped and includes twoend portions connected to the cross member. With the above arrangement,the shoulder anchor is supported by the cross member via the firstsupport portion, and the winding device is supported by the cross membervia the second support portion. In this case, each of the first supportportion and the second support portion is securely connected to thecross member at two locations, i.e., at both end portions thereof. Also,each of the first support portion and the second support portionpreferably has a shape like the letter U. This makes it possible toattach the shoulder anchor to the first support portion so as not toprotrude outward beyond an outer perimeter of the first support portion,and to attach the winding device to the second support portion so as notto protrude outward beyond an outer perimeter of the second supportportion. Therefore, it is possible to protect the shoulder anchor andthe winding device.

Further preferably, the vehicle further includes a grab bar including anend portion attached to the cross member. By attaching an end portion ofthe grab bar to the cross member in such a manner as described above, itis possible to fix the position of the end portion of the grab bar, andto prevent the grab bar from protruding in the width direction of thevehicle.

Further, preferably, the grab bar includes another end portion attachedto the second support portion. In this case, it is possible to mutuallyenhance the connection strength of the grab bar and the second supportportion to the cross member.

Preferably, the vehicle further includes a fastener connecting thesupport portion and the cross member to each other. In this case, it iseasy to remove the cross member from the support portion when thevehicle is to be transported. This makes transportation of the vehicleeasy.

Further preferably, the second seat portion includes a headrest portion,and the cross member overlaps the headrest portion in the front view. Inthis case, it becomes possible to easily support the headrest portion ofthe second seat portion in the front row by the cross member.

Further, preferably, the vehicle further includes a steering wheel infront of the first seat portion, and with this arrangement, the shoulderanchor and the winding device are disposed adjacent the first seatportion in the width direction of the vehicle. In this case, theshoulder anchor and the winding device are on a side closer to the firstseat portion when viewed from the second seat portion, and therefore,the arrangement sufficiently reduces sway of the passenger sitting inthe second seat portion toward the first seat portion. Thus, the driverdrives the vehicle more comfortably.

The above and other elements, features, steps, characteristics andadvantages of the present invention will become more apparent from thefollowing detailed description of the preferred embodiments withreference to the attached drawings.

The vehicle 10 further includes a transfer mechanism 286 that transmitsmovements of the steering wheel 28 to the pair of front wheels 16. Thetransfer mechanism 286 is preferably any appropriate conventional rackand pinion type transfer mechanism, for example.

According to the vehicle 10 described above, the frame portion 20 andthe roll-over protection cage 22 are connected by the pair of supportportions 90 a, 90 b that extend in the up-down direction and areconnected to each other by the cross member 92. This makes it possibleto improve the rigidity of the vehicle 10 as a whole and to securely fixthe cross member 92 in the vehicle 10 even if the vehicle 10 isincreased in size in the fore-aft direction by including the front row12 and the rear row 14 arranged in the fore-aft direction. In addition,the cross member 92 that is securely fixed to the vehicle 10 is locatedbetween an upper end of the shoulder anchor 220 and a lower end of thewinding device 218 in the front view. Therefore, it is possible todispose both of the shoulder anchor 220 and the winding device 218adjacent the cross member 92, and to securely support the shoulderanchor 220 and the winding device 218 by the cross member 92. The crossmember 92 extends in the width direction of the vehicle 10 between thefront row 12 and the rear row 14, while the cross member 92 connects thepair of support portions 90 a, 90 b to each other at positions higherthan their centers, in the up-down direction, of the pair of supportportions 90 a, 90 b. This makes it possible to dispose the cross member92 sufficiently above the seat surfaces (upper surfaces of the seatbottom portions 172, 176, 180) of the seat portions 166, 168, 170 in therear row 14. As a result, it is also possible to dispose the windingdevice 218, which is located at a position lower than the cross member92, sufficiently above the seat surfaces (upper surfaces of the seatbottom portions 172, 176, 180) of the seat portions 166, 168, 170 in therear row 14. In other words, neither of the cross member 92 and thewinding device 218 is disposed at a position lower than the knees of thepassengers sitting in the rear row 14, and the arrangement ensurespassenger comfort in the rear row 14 (see FIG. 7 and FIG. 13).

Each of the first support portion 108 and the second support portion 110is securely connected to the cross member 92 at two locations, i.e., atboth end portions thereof. Also, each of the first support portion 108and the second support portion 110 is preferably U-shaped orsubstantially U-shaped. This makes it possible to attach the shoulderanchor 220 to the first support portion 108 so as not to protrudeoutward beyond an outer perimeter of the first support portion 108, andto attach the winding device 218 to the second support portion 110 so asnot to protrude outward beyond an outer perimeter of the second supportportion 110. Therefore, it is possible to protect the shoulder anchor220 and the winding device 218.

Each of the grab bars 116, 118 includes one end portion attached to thecross member 92. This fixes the position of these end portions of thegrab bars 116, 118, preventing the grab bars 116, 118 from protruding inthe width direction of the vehicle 10. The grab bars 116, 118 includeother end portions attached to the second support portion 110. Thisarrangement mutually enhances the connection strength of the grab bars116, 118 and the second support portion 110 to the cross member 92.

Since the support portions 90 a, 90 b and the cross member 92 areconnected by the fasteners 101, it is easy to remove the cross member 92from the support portions 90 a, 90 b when the vehicle 10 is to betransported. This makes transportation of the vehicle 10 easy.

The seat portion 138 includes the headrest portion 160, and the crossmember 92 overlaps the headrest portion 160 in the front view.Therefore, it becomes possible to easily support the headrest portion160 of the seat portion 138 in the front row 12 by the cross member 92.

In the width direction of the vehicle 10, the shoulder anchor 220 andthe winding device 218 are located adjacent the seat portion 136. Inother words, the shoulder anchor 220 and the winding device 218 arelocated on a side closer to the seat portion 136 when viewed from theseat portion 138. Therefore, this arrangement sufficiently reduces swayof the passenger sitting in the seat portion 138 toward the seat portion136. Thus, the driver drives the vehicle 10 more comfortably.
